| Popis: |
We present measurements of two-dimensional photonic crystals in a waveguided geometry, using photoluminescence from emitters inserted in the guiding heterostructure as an internal light source. A complete set of measurements is given, including quantitative evaluation of the transmission, reflection and also diffraction coefficients of the samples. Their behaviour is shown to follow mostly the pure 2D theory. Capitalizing on the measured properties, we fabricated one-dimensional cavities. The cavity modes are probed through transmission measurement. The measured quality factor leads to an estimation of the reflectivity of the mirror of the order of 95%. We also designed and fabricated disk cavities surrounded by circular Bragg mirrors. The resonances are probed by exciting the photoluminescence of quantum dots placed inside the cavity. Resonances with quality factors up to 650 are found corresponding to the confined Quasi-Radial Modes. |
